Taw qhia
Ethyl ethynyl carbinol (Ethyl ethynyl carbinol) yog cov organic compound nrog cov tshuaj formula C6H10O. Nws tau txais los ntawm kev ntxiv ib pawg hydroxyl (OH pawg) rau pentyne. Nws lub cev muaj zog yog raws li nram no:
Ethyl ethynyl carbinol yog cov kua tsis muaj xim nrog cov ntxhiab tsw. Nws yog soluble hauv dej thiab ntau cov kuab tshuaj organic xws li cawv, ethers thiab esters. Nws muaj qhov qis dua qis dua, yog sib dua tshaj li dej, thiab muaj qhov ntau dua npau npau.
Ethyl ethynyl carbinol muaj qee yam kev siv hauv cov organic synthesis. Nws tuaj yeem siv los ua cov khoom pib thiab nruab nrab hauv cov organic synthesis, thiab feem ntau siv rau hauv kev npaj cov khoom sib xyaw carbonyl. Nws tuaj yeem koom nrog alkyd esterification, olefin ntxiv, saturated hydrocarbon carbonylation cov tshuaj tiv thaiv. Tsis tas li ntawd, 1-pentyn-3-ol kuj tuaj yeem siv rau hauv kev sib xyaw ntawm cov dyes thiab tshuaj.
Txoj kev npaj Ethyl ethynyl carbinol tuaj yeem ua tiav los ntawm cov kauj ruam hauv qab no: ua ntej, pentyne thiab sodium hydroxide (NaOH) yog reacted hauv ethanol los tsim 1-pentyn-3-ol sodium ntsev; Tom qab ntawd, 1-pentyn-3-ol sodium ntsev yog hloov mus rau hauv Ethyl ethynyl carbinol ntsev los ntawm acidification cov tshuaj tiv thaiv.
Thaum siv thiab tuav Ethyl ethynyl carbinol, koj yuav tsum tau xyuam xim rau cov ntaub ntawv kev nyab xeeb hauv qab no: Nws yog khaus thiab ua rau khaus thiab raug mob ntawm daim tawv nqaij thiab qhov muag, yog li koj yuav tsum hnav cov khoom tiv thaiv tus kheej tsim nyog, xws li hnab looj tes thiab tsom iav. Tsis tas li ntawd, nws yog flammable thiab yuav tsum tau zam los ntawm kev sib cuag nrog qhib nplaim taws los yog kub qhov chaw, thiab khaws cia kom zoo. Ib qho ntxiv tuav lossis khaws cia cuam tshuam nrog qhov sib xyaw yuav tsum tau ua raws li cov txheej txheem kev ua haujlwm nyab xeeb.
